Thermos kettle pump not working. What should I do if the water supply button does not work in the thermopot? Thermopot manual pump does not pump water

A thermopot is essentially an electric kettle combined with a thermos. Unlike an electric kettle, an additional heating element was added to the design of the thermopot, used to heat water and a controller that controls its operation and maintains the temperature within 75º - 95º C. Many thermopots also have a pump for water supply. The tank for heating water is covered with a casing that protects against burns and serves as the outer shell of the thermos, reducing the consumption of electricity to maintain the temperature. If the housing is made of metal, it is grounded (see wiring diagram) to protect against electric shock. All the main components of the thermopot are located at the base of the case.

Electric circuit of thermo pot

Schematic diagram of thermopots various models and manufacturers is not significantly different from the one below:

Diagram of a thermo pot with one temperature sensor (Fig. 1)

Schematic diagram of a thermo pot with two temperature sensors (Fig. 2)

Details and units used in thermopot:

Water pump - an electric motor with an impeller in a sealed housing, when turned on, it supplies water to the thermopot spout. Power supply 12V DC. It is fastened with screws to the body with a bracket through a silicone gasket, which protects the motor from overheating. The impeller itself is rotated by a magnet, very interesting design, the magnet on the motor shaft rotates the impeller with a similar magnet.

Temperature sensor (thermal switch) - normally closed, when the required temperature (95º - 125ºC) is reached, it opens the contacts. Designed for switching 10A 250V. It is attached to the surface of the tank with screws; for better thermal contact, thermal paste is used, such as KPT-7.

Thermopot heater - a heating element consisting of two heating elements (boiling, heating) is attached to the base of the tank.
Resistance of heating element 650-700 Ω, heating element resistance 65-90 Ω.

The principle of operation of an electric thermopot

The heating element of water heating is always on, when the temperature in the tank drops to 75º (for example, if cold water is added), the heating element of boiling is turned on. When the temperature reaches 95º, the thermopot turns off the boiling mode and switches to the heating mode. Power consumption in heating mode ≈70 watts, in boiling mode 1000 - 2500 watts, depending on the thermopot model.

In case of boiling water in the tank, the temperature rises sharply and when it reaches 125º the thermal switch (F1 fig. 1, FU1 fig. 2) breaks the power supply circuit of the thermopot until the temperature drops.

The main malfunctions of the thermopot and solutions

Thermopot does not turn on

When the thermopot is turned on, the boiling mode does not turn on, the water pump works.
Boiling heater is out of order, ring, replace if out of order. Faulty relay K1 (fig.1,fig.2). Breakage of the power supply circuit of the heating element is possible.
When the thermopot is turned on, the boiling mode does not turn on, the water pump does not work.
Check temperature sensors (F1 fig.1, FU1 or SF2 fig.2). Maybe damaged wire or power cord plug. Possible broken wiring in the power circuit.

Thermopot won't turn off

Thermopot boils water constantly- the temperature sensor is faulty (SF1 Fig. 2). Faulty relay K1 (fig.1,fig.2).

Thermopot often turns on in boiling mode

The heating element of water heating is out of order, ring, replace if it is out of order. Possible break in the power supply circuit of the heating element.

Thermopot does not boil water

Thermopot takes a long time to boil. Boiling heater is out of order, ring, replace if out of order. Faulty relay K1 (fig.1,fig.2). Breakage of the power supply circuit of the heating element is possible.

- this is a small household appliance that combines the properties of two devices at once - electric kettle and a thermos.

The main advantage is the ability to boil water and keep its temperature in a given mode, as well as the ability to repair the thermo pot with your own hands if such a need arises.

How it works

Note that, despite the presence of a lot of advantages, the thermopot also has specific disadvantages, in particular:

high cost - much more than a standard electric kettle;
low boiling speed (compared to electric kettles);
increased energy costs due to the constant inclusion and the need to work in the temperature maintenance mode.

The device consists of a housing, external elements of the control panel and internal technical devices.

The body is made from various materials(depending on the model of the unit):

glass;
plastic;
metal;
ceramics.

A combination of these materials is also possible.

Appearance of thermopot

The body shape also depends on specific model. Often, this is either a half-cylinder or a rectangle.

For comfort Maintenance and care, almost all models are equipped with a removable flask into which water is poured.

The device is also equipped with a control panel with buttons that allow you to set certain operating modes.

Since the unit in question combines two traditional devices at once - a kettle and a thermos - there are two heating elements inside at once:

one is directly responsible for bringing water to a boil;
the second performs the function of maintaining the temperature at a given level.

Due to the fact that the thermopot is quite heavy and overall, manufacturers supply it with a special button for water supply. This is very convenient - just place a mug under the drain hole and press the drain button. A special water pump is responsible for pumping water.

All thermopots are also equipped with electronic filling - namely, a control chip that processes user commands, and a power supply.

Main knots

Basic principles of operation

The device works in the following order:

water is poured;
the top cover is closed;
a heating element used to boil water heats water to a temperature of 100 degrees;
as soon as the water reaches the above temperature, the thermal fuse that protects against overheating turns off the device;
water begins to cool down to the temperature set by the user;
the “case” includes a second heating element, designed to maintain a given temperature regime.

circuit diagram

If, you need to familiarize yourself with the circuit diagram.

Scheme this device not too complicated - even a non-professional electrician can “read” it.

It can be used to investigate the causes of failure of devices from such popular manufacturers as:

Polaris;
Vitek;
Elenberg;
Scarlett and others

circuit diagram

Deciphering the main symbols used in the diagram

Decryption:

S1 and S2 are temperature switches from the KSD 302 series, the first one is located in the middle of the stainless steel tank and is connected in series to transfer the supply voltage of 220 Volts, the second one is located at the bottom of the thermopot - current flows through it to the main heating element;
F1 - thermal fuse;
TH2 - an additional water heating coil, which should be checked to answer the question why the thermopot does not keep the temperature;
relay S1.1 connected in parallel with the reboil coil;
ТН1 – spiral of the main heating element;
VT1, VT2 - transistors on which there is a relay for controlling the on and off times, which open under the action of a charged capacitor C3;
C3 - an electrolytic capacitor, charged by pulses from VD6 by briefly pressing the S4 button;
K1 - relay winding through which flows electricity and switches S1.1;
C1, C2, VDS1 - voltage rectifiers supplying the time relay circuit.

Notes:

C1 serves as an excess voltage damper;
C2 - performs smoothing of electric current ripples resulting from the operation of the VDS1 bridge rectifier;
some units do not use C1, but a step-down transformer.

Private malfunctions

Like any other piece of household appliances, thermopot has a list of the most common problems.

Here are some particular malfunctions of the thermopot and parts, the replacement or repair of which with your own hands in this case should be carried out first of all:

The control panel does not light up completely, the device itself does not start and does not work.

In this case, the cause of the failure may be:

thermostat located, depending on the model, either on the bottom or on the side of the device;
fuse;
broken wires and connections.

Only the temperature maintenance mode works, while the main boiling of water does not function.

You can troubleshoot by checking:

bottom thermal switch;
the main heating element designed to heat water up to 100 degrees.

The reverse situation is that boiling up to “hundred” works, but the heating does not function.

There is only one advice - check all the elements of the electrical circuit by turning Special attention to the board module.

Pressing the water button does nothing.

The problem lies in the pump - it is necessary to disassemble the thermopot, following the instructions below, and find out the true cause.

Disassembly of the thermo pot - step by step instructions

What to do if the device does not want to turn on, does not heat water, leaks or does not heat up? In this case, it is recommended to disassemble the unit by following these step-by-step instructions:

disconnect the device from the electric current network;
drain the water in the inner flask;
turn the unit upside down;
remove the plastic plug from the latches with a flat screwdriver, knife or other improvised item;

plastic plug

with help Phillips screwdriver unscrew all screws;
then remove the pallet (for the convenience of reassembly, it is recommended to photograph the disassembly process so as not to get confused);
after removing the pan, access to the water pump will be open, from which you need to remove the hoses held on by plastic ties - you can simply cut them off with scissors;
then you need to remove the hoses from the pipes from the printed circuit board;
next, you can start unscrewing the printed circuit board, which is held on small bolts;
there is a gasket under the board - it must be removed in order to gain access to the heating coil;

View of the board with the cover removed

to gain access to the heating element, unscrew the last 8 screws, then remove the protection;
check the parts that have been accessed with a multimeter in the order indicated later in the article for various kinds malfunctions;
for reliability, before reassembly, it is recommended to clean the heater from scale, as well as inspect the printed circuit board, if necessary, replace the capacitors with new ones;
reassemble in the same manner as disassembly.

Detailed analysis of repair parts

There is a certain list of internal parts of the thermopot, which are recommended to be inspected first.

Network wire

The 220 volt power cord may be bent or make poor contact with the three-pin connector located inside the case.

First you need to check the wire itself directly in the “ringing” mode using a multimeter or by connecting the cable to some other device.

multimeter

If the cable is operational, you should check the presence of voltage at the output after the transformer.

Microcircuits

Most models are equipped with two electronic modules:

power board;
control board.

Control board

In fact, the power board is a power supply unit, from which an electric current of the required parameters is supplied to each element of the thermopot.

To repair both boards, you must first inspect them for:

swollen capacitors;
burnt resistors;
unusable fuses;
torn contact tracks, etc.

All damaged elements must be replaced with new ones, after taking care of their purchase on the radio market. Damaged tracks can be repaired by tinning with a household soldering iron.

The most common problem here is a blown fuse. It can be identified by a broken thread inside the glass case.

If the fuse is in order, you should check the resistors and diodes with a tester.

Water pump repair

What to do if a thermopot runs or, conversely, when you press the water drain button, nothing happens? In this case, you should get to the pump and start testing its performance.

This is done by simple pairwise dialing of contacts.

To check the performance, you can also apply a standard voltage of 12 volts, taking it, for example, from powerful batteries or from a car battery.

Also, the corresponding voltage is given out by power supplies installed in the system units of personal computers.

Repair of heating elements

If the heating or main boiling does not work, the malfunction may be a failed heating element. Self repair it is not recommended to produce a heating element - it is easier to buy a new one. The cost of heating coils starts from 2000 rubles.

Teng disassembled

Analysis of common situations and ways to solve them

Here is a list of the most common problems - with instructions for solving them.

Thermopot provides constant boiling

It is not uncommon for a situation where The opposite is also possible - when the unit is turned off at a time when the liquids are still far from the start of boiling.

The problem lies in the malfunction of the thermal switches. They are located on the bottom of the device and on the side of the case.

The main problem of their inoperability is the manufacturer’s application of a small amount of thermal paste, due to which the thermal relay starts to work incorrectly due to poor contact.

The relay’s performance is checked with a conventional multimeter - for this, it is connected to the contacts of the thermostat and set to ohmmeter mode. The tester should show a resistance of 0 ohms.

Thermal relay

The thermopot drains the liquid on its own

Some face next problem- immediately after plugging into the socket, the thermopot drains water from the flask, starts to buzz, a characteristic smell of burning appears. How to fix such a shortcoming?

The problem here is the water pump. First you need to disassemble the thermopot itself (see instructions above) and get to the location of the pump. The next step is to disassemble the pump.

After unscrewing the two bolts on the pump itself, you can access the impeller and magnet. In order not to buy a new pump, you can fix the old one - to do this, you need to disconnect the blades from the magnet and clean them from scale with a rag or soft cloth. You should also inspect the magnet itself - it often accumulates the smallest metal particles that prevent normal operation.

If these steps have been taken, but the unit is still leaking, you should buy a new pump.

Otto Dietrich: I press the Block button, then pour water. The pump twitches, the button unit turns off. What could be

Urzhum: Obviously, the bottom of the thermopot from the hostess scooped up water in the sink. Turned it on and didn't wait for the water to dry. As a result, the short circuit and failure of the transistor. The instruction must be read at least once from cover to cover, there is a warning on what to avoid. Many have not a single breakdown even after 7 years of operation. The coating peels off over time - because they pour cold water into the hot bowl of the machine. There is zero attention to this, the mesh filter delays delamination, it must be monitored and removed from the mesh.

How to repair a thermopot with your own hands

Surely, many in the kitchen you can find not a simple electric kettle, but a thermos or the so-called "thermal pot".

Advantages and disadvantages

In addition, a thermopot can save not only your time (you do not need to wait for the water to heat up), but also electricity (you do not need to turn on an electrical appliance every time someone in the household wants to drink hot tea or brew porridge or other food).

A large amount of liquid, four to five liters, boil more time than in an electric kettle;

Causes of failure

From this video, you will learn what causes of breakage exist in thermopots. Recommended for viewing!

Repair of various parts of the thermopot

Network cord. To carry out the repair of the power cord, it is necessary to unscrew several screws to which the body of the thermopot is attached. Inside there is a special block, and visually inspect all internal parts. Carefully separate the cord and check it with a tester, if it is faulty, we replace it;

Chip. An ordinary thermopot has two microcircuits: a power supply and a control one. We inspect them visually in order to determine swollen capacitors, burnt transistors, broken fuses, and other breakdowns. In order to replace elements that are out of order, it is necessary to use soldering; it does not restore contacts in the presentation methods. Initially, when repairing a microcircuit, you need to check whether all the fuses are in place and whether they are intact. consists in its electronic stuffing. Since there was a short circuit in it;

Capacitor. Much easier to deal with a broken capacitor. Since they swell and are easily determined on appearance.

Diodes. It is much more difficult to determine the breakdown of diodes, I am glad that they break quite rarely. It is necessary to sample the element and call its sides in order to understand whether it is in working condition;

Board tracks. In order to bring the broken tracks on the board into working condition, they are lightly sanded to make the top layer of varnish out of them. The shiny surface is aligned and covered with a layer of solder;

Water pump. Also, each device contains a special pump for water supply, both automatic and manually.

Panasonic thermopot repair does not pump water

For a Vitek thermopot, a new pump costs about $ 30. An experienced electrician can easily determine which part has failed. It is also necessary to check the thermopot pump for suitability.

Do-it-yourself thermopot repair does not pump the pump.

How to repair a thermopot with your own hands.

Today, in many areas of human activity, various technological devices occupy a priority place.

The field of cooking also has many technological innovations to make our lives easier.

Surely, many in the kitchen you can find not a simple electric kettle, but a thermos or the so-called “thermal pot”.

This word comes from in English and literally means a temperature pot or thermos.

Advantages and disadvantages.

The main advantage of a thermo pot over an electric kettle is that you can not only boil water in it, but also store it, preserving it. high temperature like in a thermos.

You can set the temperature yourself.

Most models are equipped with four water heating modes.

It is able to maintain the temperature you need for several hours.

The water remains hot, as if it had just boiled, but if you need, you can choose a lower setting.

By purchasing a thermopot, there will always be water with the required temperature, for example, for brewing a cup of tea or cooking baby food for a child.

A large amount of liquid, four to five liters, boil more time than in an electric kettle.

Its cost is several times more than a simple electric kettle.

Causes of breakdown.

From this video, you will learn what causes of breakage exist in thermopots. Recommended for viewing.

Despite the fact that such a device has an excellent and solid construction, they break quite often due to Bad quality their electrical nodes.

Since the cost of a new, such a kettle is not small, in many cases it is best to repair it yourself or by contacting the master and not overpay a significant amount of money to buy a new kettle.

The main reasons why a thermopot can fail, as well as methods for their elimination.

No indication special panel thermopot control does not turn on.

It is necessary to check the integrity of all wires, as well as check the operation of the thermal fuse and the safety switch.

The thermo pot reboil button does not execute the command and does not boil water when it is first turned on, as well as when water is poured into it. It is necessary to check the operation of the thermal switch located at the bottom of the tank.

Lack of operation of the device, in all modes.

With this problem, the electrical circuit for forced boiling failed, actually breaking such parts as a relay with a transistor or a rectifier.

Failure of the water supply lever. Most likely, the engine for supplying water or the rectifier diodes on the engine power circuit are not working.

This is a list of the main thermopot malfunctions that have a similar design.

Vitek thermopot board.

Repair of various parts of the thermopot.

Network cord. To carry out the repair of the power cord, it is necessary to unscrew several screws to which the body of the thermopot is attached. Inside there is a special block, and visually inspect all internal parts. Carefully separate the cord and check it with a tester, if it is faulty, we replace it.

Capacitor. Much easier to deal with a broken capacitor. Since they swell and are easily determined by appearance. Diodes. It is much more difficult to determine the breakdown of diodes, I am glad that they break quite rarely. It is necessary to sample the element and ring its sides in order to understand whether it is in working condition.

Water pump. Also, each device contains a special pump for supplying water, both automatically and manually. For a Vitek thermopot, a new pump costs about $ 30. An experienced electrician can easily determine which part has failed. It is also necessary to check the thermopot pump for suitability.

Repair of heating elements.

If the heating elements break, in almost all cases they must be replaced.

New heating elements start at $40.

The standard device contains several thermal switches.

One is assigned to control water parameters, and the second serves to protect against turning on the thermopot in the absence of water in it.

The thermal switch works in such a way that the surface of the tank and the flange are in contact.

To improve contact, a special lubricant is used, similar to that used in personal computers.

Upon reaching certain temperature switch, its contacts close, as soon as the temperature decreases, their conductivity is restored.

These thermopot components can be easily found, as their description is made on the body and marked accordingly.

What are the features of the Karcher vertical clothes steamer, this article will tell. do not miss your chance to get acquainted with useful material.

Here. you will be able to find a description of the portable gas heater for a tent.

But more often than not, the manufacturer also adds an additional temperature fuse, which is a small cylindrical piece that fits snugly against the wall on the bike.

Works exactly the same as a conventional thermal switch.

In order to check the operation of a metal contact, it is necessary to make a dial-up book, having previously completed the working contacts from the thermopot, they will be short-circuited.

Repair tips.

The internal stuffing of most thermopots is slightly different from each other.

And the simplest models are easy to self-repair.

Repair of Vitek thermopot can be carried out according to standard schemes.

To repair this device, on their own you need to soberly evaluate your knowledge and experience.

And do not try to solder microchips that require a hot air gun with an inappropriate soldering iron.

To begin with, you need to know the basic techniques for working with electrical components, which often do not tolerate static electricity and high temperatures.

In order to make repairs, you will need tweezers, a tester, a screwdriver with a voltage indicator, as well as a soldering iron and other tools.

How to repair a thermopot with your own hands.

All thermoses-heaters have a similar device and principle of operation, differing only additional features, as well as the material of manufacture. The working parts of the thermopot are enclosed in a case, and in order to repair the thermopot, it will have to be removed. Water is poured into a stainless steel tank, in the bottom of which two heating elements are built. One of them produces the main heating to the state of boiling water, and the second only heats the water. There is also a general conclusion. Each wire is covered with ceramic protection - "beads". This prevents the wires from coming into contact with the metal container.

On the side you can see a cylindrical object. This is a thermopot engine (water pump) designed to supply water. IN different models the voltage drop across the motor is between 8 and 24 volts.

It is impossible not to notice the electronic board on which the circuit (time relay) is mounted, which is responsible for re-boiling. Also, the circuit is needed to convert the voltage for the pump and relay. You can solder the broken contacts on the circuit with your own hands, repairing them in this way.

In addition to the main board, the thermopot has a control board. With its help, the buttons for water supply, reheating work, and red and LED indicators are connected to it, indicating what mode the thermopot is in.

great value in all heating appliances has a thermal switch. It is installed in the bottom and on the side of the water tank. In case the thermal switch does not work, a thermal fuse is also provided. This allows you to prevent overheating and damage to the thermal pot if it is turned on empty.

Knowing the location of all the main parts of the thermopot, it is much easier to identify the problem and make repairs.

It is even better to study the diagram in order to understand what is connected how, and what details can be changed. In some cases, repairs do not make sense, and even specialists do not undertake it.

We disassemble the thermopot.

It is immediately worth noting that it is easiest to remove with your own hands upper part thermos heater. To disassemble the thermopot, it is necessary to find and unscrew the screws located at the bottom of the device. After that, the case can be easily removed. First you need to visually inspect the board. It happens that a crack is found on the soldering, and the soldered element disappears. In this case, you should use a soldering iron to fix everything as it was.

Be sure to inspect the thermal switch located in the bottom. Its condition is checked with an ohmmeter.

Do-it-yourself thermopot repair

The working device has almost zero resistance. A defective part must be replaced with a new one. And then the question becomes, where to buy necessary spare part. Often this can be done only through online stores.

To remove the pump in case of a malfunction, it is necessary to disconnect the inlet pipe from it and unscrew the bolts. Sometimes cleaning the impeller and magnet with a regular cloth gives its results. In some cases, repairs will no longer help, and you will have to resort to replacing the thermopot.

How to fix some crashes.

We will analyze what malfunctions a thermopot can have, and how to fix them with your own hands.

The indicator panel does not turn on and the appliance does not work at all. In this case, check all wires, all connections, as well as the fuse and thermal regulator. If there are several reasons, then the repair will be more difficult to perform.

Only the reboil button works. The main first boil is not carried out. In this case, check the thermal switch located in the bottom.

The first boiling works, and when boiling again, the thermopot does not turn on. You should inspect the circuit on the main board.

Water can only be heated, the thermopot does not boil. Most likely, the heating element burned out or the contact broke.

The water supply function has stopped working. There is a problem with the pump power circuit. Quite often, the spiral also burns out additional heating, after which the motor is no longer supplied with voltage.

If the spirals of the heating elements are burned out, then it is not economically feasible to repair the thermopot. Firstly, it is difficult to disassemble the tank, and secondly, the cost of insulation and high-resistance wires is quite high.

When the repair is completed, it is necessary to check the electrical safety of the device. To do this, it is necessary to measure the resistance between the plug contacts and the tank, as well as between the plug contacts and the outer casing. The resistance must be infinite.

Why is the water supply in the thermopot not working.

All home appliances designed to provide comfort to the user. As we get used to easy exploitation, we get frustrated when a feature doesn't work. Quite often, the pump does not work at the thermopot. As a result, water enters the cup manually. It seems that in general the equipment works, but a small breakdown makes it difficult to use the device. Today we will understand why the water supply in the thermopot does not work.

What to do if the pump does not pump.

Work begins with the dismantling of the bottom cover of the device. Usually it is mounted on several bolts that need to be removed. Then you should disassemble the pump, it will be more convenient to do this if you remove the inlet pipe. Next, you need to check the condition of the connecting tubes. Namely, whether they are clogged with scale. If necessary, remove and clean them.

The next step is to remove the magnet from the engine. All parts must be thoroughly cleaned from scale and debris. This is best done with a napkin or cloth. When disassembling the pump and engine, do not forget to keep the gaskets intact. They will come in handy when assembling the device.

After such simple actions, the thermopot must again supply water. If the problem persists, you will most likely need to replace parts.

The pump does not work and the temperature is not maintained.

If the breakdown is complex, then look for the cause of the malfunction in the heating element. Most often this indicates overheating of the heating element. In this case, work begins with the dismantling of the top cover. Next, we perform the following steps.

Turn the thermopot over and remove the support ring. To do this, you will need a screwdriver and a little effort.

3. Under the lid, all the insides of the thermopot are hidden. We need to remove the upper part of the equipment case.

5. The next step is to remove the heating element. It is important to proceed carefully here. Contacts can be released with socket wrench, and with a Phillips screwdriver - the heating element screed.

6. It remains only to ring the heating element, replace it and make sure it works.

Be careful when replacing the heating element. Their size may vary depending on the model. For example, there are heating elements 150 or 160 mm. Therefore, before buying, you should clarify what size you need for your thermopot.

Thermopot is a duet of a thermos and an electric kettle, which is designed to store water at a constant temperature (close to boiling). This is achieved by self-reheating the liquid when it cools below a predetermined level. The process occurs continuously as long as there is liquid in the kettle, or until it is forcibly disconnected from electrical network. But, like any other electrical appliance, this technique also fails. However, do not be upset and immediately carry it to the service. If the breakdown is not very serious, then it is quite possible to repair the thermopot with your own hands.

The principle of operation of the thermopot

To understand the causes of breakdowns and better understand how to repair a thermopot, you should familiarize yourself with the principle of its operation. First, the device boils water like a regular kettle, and then the control module of the device comes into action, which, by means of a thermostat, monitors the set minimum temperature of the liquid and, as soon as it drops below the norm, immediately switches on re-boiling. For heating, the thermopot uses a second heating element, which is always less powerful than the main one, since its operation is very fleeting.

Due to the large dimensions and considerable weight of the thermopot, for pouring boiling water into a cup built-in pump. It can be powered by electricity, like Marta products. Such a pump allows the possibility of setting autofilling through the control module. There is also a mechanical (manual) pump, like MAGNIT RTP-002, then the liquid is pumped into the mug manually through a special spout. Many models (for example: Vitek vt 1187 gy, Saturn ST-EK8032, Mystery MTP-2403 and Bravo TA-65 S thermos kettle) have both types of pumps.

In addition to the above details (control module, thermostat, two heating elements and a pump), the circuit necessarily includes thermostat(sometimes two, like Maxwell and Scarlett products) and thermal fuse. Their main task is to prevent overheating and ignition of the device. For the correct operation of the electric pump and the control module, a power supply with step down transformer.

Mostly all thermopots work one by one general scheme and differ only in details. For example, some models are equipped with an auto-on timer. IN budget options there may be no low-power heating element (as in the products of Vitek and Magnit). But there are thermo pots (for example, a thermos kettle Polaris PWP 4012D), which combines almost all useful functions.

Disassembly of the thermopot

To quickly find and fix faults, the thermopot must be disassembled. And since all models have a similar structure, there is a general algorithm of actions. Dismantling the device is not difficult, for this it is enough to follow the following instructions:

disconnect the device from the mains and pour water out of it;
unscrew the screws at the bottom;
remove the clamps from the ring and unscrew the loose screws;
remove the pallet;
dismantle the pump, having previously disconnected the hoses from it;
remove the cover of the thermopot for the convenience of installing the device on the table upside down;
unscrew the printed circuit board and move it to the side so as not to interfere;
unscrew the screws hidden under the board gasket;
remove the bottom together with the pallet;
unscrew 8 more screws holding the protective cover;
remove the cover and remove the heater.

Advice! So that the assembly of the thermopot after repair does not cause problems, you should fix the location of the wires and parts on the camera.

Typical breakdowns and their elimination

For devices manufactured according to the same scheme, typical faults. How to find and eliminate them will be described in the pictures below.

Doesn't turn on

If the device does not turn on, then the matter in violation of the contacts of the electrical circuit. The only question is where the break occurred. You need to start checking with the power cord. If it is unusable, replace the wire with a new one. Then all connections of both thermal switches must be checked. An emergency opening may have occurred, and due to a faulty thermostat, the contacts did not return to their place. Also, the connection at the thermal fuse may not be restored. To check, you need to disconnect the questionable part and close the wires directly. If it works, the defective part is replaced with a new one.

Constantly boils water

The situation when the water is constantly boiling and the device does not turn off can only occur in the most budget models with one thermostat. It is because of its breakdown that the thermopot does not turn off after boiling. Here you should immediately, without any checks, change the thermal switch. In good and reliable samples, there is always a backup thermostat. And some manufacturers install additional control in the form of a thermal fuse, which will insure if for some reason both protections do not work, and the kettle constantly boils water.

Shuts off before boiling

Usually this happens only with devices that have worked for more than one year. It's connected with loss of its properties by a bimetallic plate in the thermostat, which over time begins to respond to a lower temperature than planned. To remedy the situation, you can try to temporarily bend the contacts at the plate. A best solution the thermostat will be replaced.

The fact that the thermal pot has stopped boiling water may be to blame commonplace scale. Settling in a thick layer on the heating element, it lowers its thermal conductivity. The heating element gradually starts to overheat. At some point, the thermostat sees this as a fire hazard and opens electrical circuit moments before the water boils. You can get rid of scale on the heating element by simply boiling the solution citric acid. If this does not help, then you will have to disconnect the heater and clean it with a knife.

Important! Thermopot may not boil water also due to leakage in the flask. Even a few drops of liquid can cause overheating. The search for cracks is carried out visually, and it is more reliable to eliminate them in the workshop.

Other causes of breakdowns can be bad contacts. In this case, all connections to the wires of the heating element and the thermal switch should be checked. If necessary, the contacts are soldered.

Water button not working

If the water supply button does not work, then there may be several reasons. First of all, this could be due to blockage in the system. Garbage is most often particles of scale that settle on the walls of pipes and hoses, gradually reducing their clearance. This eventually leads to the fact that the pump does not pump water.

For descaling you also need to use citric acid or vinegar by boiling water with them in the apparatus. In the case of insoluble waste, complete disassembly pump and the entire water system. To do this, disconnect all hoses and blow through them. The pump itself should be disassembled as follows:

disconnect it from the body of the device;
unscrew the impeller and clean the scale from it;
free the magnet from dirt.

Advice! If, after cleaning, everything also does not pump the pump, this may mean that the winding on the motor has burned out. And it is better and more reliable to eliminate such breakdowns in the service.

The liquid filling button does not work and in case of bad contacts on the key itself or at the junction of the wires with the electric pump. To eliminate it is necessary to check the entire circuit for breaks. If the second heating element fails, the electric pump motor is no longer supplied with voltage.

Important! If the thermopot has only one electric pump, and the water supply does not work, then first of all you need to check the serviceability of the outlet and the presence of electricity in the house.

Doesn't heat water when light is on

When the device does not heat water when the indicator is on, the first thing to do is to check the heating element. But if the heater is working, then the reason may be wiring diagram. That is, the thermopot does not heat the water, but the light bulb is on if there is a fuse in the circuit after the indicator that has blown. To correct the problem, the defective part must be replaced.

Other malfunctions

With prolonged or incorrect operation of the thermal kettle, other problems may occur.

Reboil not working- the cause must be sought in the additional heater and control module.
No main boil whereas re-boil button works- Check the thermostat.
Thermopot only works for heating, but does not boil - the culprit is the burnt-out main heating element.

Prevention

In order for the thermal kettle to work for many years and be constantly in good condition, regular preventive maintenance should be carried out.

Once in two months boil a solution of citric acid or vinegar. After that, thoroughly rinse the flask under running water.
Once every six months preferably disassemble the device to remove all internal debris and mechanically clean out the sediment that the acid has not coped with. Along the way, you need to check all contacts for integrity.

Advice! If the upcoming work causes uncertainty or difficulties, then you can watch the corresponding video or use the services of a qualified craftsman.

The thermopot will serve long years without serious disturbances in operation during operation according to the instructions, careful handling and periodic maintenance.
